Sell the cemetery?  Over their dead bodies...
Not many people can see the dead (not many would want to).  Twelve-year-old Johnny Maxwell can.  And he's got bad news for them:  the council want to sell the cemetery as a building site.  But the dead have learned a thing or two from Johnny.  They're not going to take it lying down...especially since it's Halloween tomorrow.
Besides, they're beginning to find that life is a lot more fun than it was when they were...well...alive.  Particularly if they break a few rules.
